IPC: F22B37/10
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent a failure as caused by imbalance of a gas flow within a duct, for example, drop in heat transfer performance and increase in stress in a group of fin tubes in a waste heat recovery boiler, between a gas turbine exhaust duct and an entrance duct of the waste heat recovery boiler.
